Lumps and Bumps on the Hand, Wrist and Fingers
Found a lump on your hand, wrist or finger? The common causes and what they mean: ganglion cysts, fatty lumps (lipomas), giant cell tumours, mucous cysts and carpal bossing, and when to see someone.
What you're feeling¶
A lump on your hand, wrist or finger is often a ganglion. That is a fluid-filled sac that grows near a joint or tendon. It can feel firm or soft, and it may change in size. Some lumps ache. Others cause no pain at all.
Where the lump sits shapes what you notice. A lump on the back of your wrist may ache when you bend your wrist back or lean on your hand to push up from a chair. A lump on the palm side of your wrist can press on nearby structures and cause discomfort with gripping. A lump in a finger, near the middle joint, can catch or block when you bend that finger, making buttons, zips and holding a pen frustrating.
The ache often flares after you use your hand. Heavy lifting, repetitive gripping or a long day of typing can make it worse. Rest usually settles it. Some people notice the lump more at night or first thing in the morning, when the hand has been still for hours.
Daily tasks can become awkward. Turning a door handle, carrying shopping bags, wringing out a washing cloth or holding a coffee cup may all pull on the lump. If the lump sits near a tendon in a finger, straightening that finger can feel stiff or slow.
Most lumps like this are harmless. Some shrink or disappear on their own, especially in children. In children under 10, ganglions are usually on the palm side of the wrist, and 69% to 79% go away by themselves within 12 to 18 months.
You do not need to rush into treatment. Watch how the lump behaves over a few weeks. Note when it aches, what makes it worse and whether it grows. That history helps your doctor work out what the lump is and what, if anything, to do about it.
What's actually happening¶
A ganglion starts when fluid from a nearby joint or tendon sheath (the tunnel that guides a tendon, like a pulley guides a rope) pushes out through a weak spot and collects under the skin. Think of it like a small balloon of thick, jelly-like fluid sitting on a hinge. The balloon itself is harmless, but it takes up space. That is why bending the wrist or finger can feel stiff or blocked, and why the lump may ache after you use your hand.
Where the balloon sits matters. A ganglion on the back of the wrist is close to the small bones and ligaments that let the wrist bend and twist. One on the palm side sits near nerves and blood vessels, so it can press on them as it grows. A ganglion in a finger often forms next to a tendon sheath, which is why straightening or bending that finger can catch.
Not every lump is a ganglion. Some lumps are fatty growths under the skin, which are usually soft and slow growing. Others grow from bone or from the tendon lining, and these can feel firmer. A detailed examination of the affected finger helps tell the difference between a ganglion in a tendon sheath, a trigger digit (a finger that clicks or locks) and Dupuytren's disease (a tightening of the tissue in the palm that pulls fingers toward it).
In children, these lumps behave differently. Ganglions on the hand go away more often than ganglions on the wrist, and most under-10s do well with simple watching rather than surgery.
The lump is not usually dangerous. But it can grow, press on nearby structures or keep aching, and that is when treatment becomes worth discussing.
What we can do about it¶
Many lumps settle without any treatment at all. If your lump is small and not painful, watching and waiting is a reasonable first step. A splint can rest an aching wrist or finger and ease the load on the lump. Gentle movement keeps the hand from stiffening while you wait. Some lumps shrink or disappear on their own, so give simple measures a fair go over a few weeks before deciding anything more.
If the lump aches, anti-inflammatory tablets or gels can calm the soreness. These are medicines that reduce swelling and pain. A cortisone injection can also settle inflammation in the tissue around the lump. For some lumps, draining the fluid with a needle is an option. This is called aspiration. It often flattens the lump quickly, though ganglions can fill up again afterwards. For a ganglion on the back of the wrist, trying at least one aspiration before considering surgery is a sensible approach.
If a lump keeps growing, keeps aching or presses on a nerve, it is worth having it assessed. Your doctor will examine the lump and may arrange scans to see what it is made of and where it sits. Some lumps are not ganglions at all. A firm lump on the back of the wrist can be a bony spur from wear-and-tear arthritis, and these are usually treated without surgery first, with splinting, anti-inflammatories and targeted injections. For a ganglion, surgery aims to remove the whole lump along with its stalk, the little duct that connects it to the joint, because leaving that connection behind makes the lump more likely to come back. Some procedures are done through small incisions using a tiny camera inside the joint, which means less cutting of the surrounding tissue.
The right option depends on what the lump is, where it sits and how much it bothers you. Bring your notes about when it aches and what makes it worse. That history, along with an examination, will help you and your doctor decide whether watching, draining, injecting or removing the lump makes the most sense for you.
What to expect¶
Most lumps on the hand and wrist are harmless, and many settle without treatment. Some shrink or disappear on their own, especially in children. Others stay the same size or come and go over months. If your lump aches after you use your hand, rest and simple measures often calm it down over a few weeks.
If the lump is drained with a needle, it often flattens quickly. Ganglions can fill up again afterwards, which is why trying at least one draining before surgery is a sensible approach for a lump on the back of the wrist. If surgery removes the whole lump along with its stalk, the chance of it coming back is lower. Leaving that connection behind makes recurrence more likely.
Some lumps are not ganglions. A firm lump on the back of the wrist can be a bony spur from wear-and-tear arthritis. These spurs are usually managed without surgery first, but even after surgery for them, symptoms can persist. That is worth knowing before you decide anything.
If the lump is caused by inflammation in the tendon lining, as happens with some forms of arthritis, the outlook depends on getting the underlying condition under control. Splinting can ease pain. A targeted injection into the inflamed tissue works better than tablets for a single affected area. Removing the inflamed lining can reduce pain and protect the tendons, and swelling that lasts 6 weeks or longer despite good medical treatment may be a reason to consider it.
For fatty growths and other soft tissue lumps, removing the lump completely usually settles the symptoms it caused. Some of these lumps can grow back if any tissue is left behind, so complete removal matters.
Whatever the lump turns out to be, the goal is a hand that works for the things you need it to do. Some people need no treatment at all. Others need a splint, an injection or surgery to get there. Your doctor will talk you through what the outlook looks like for your specific lump once they know what it is.
When to see someone¶
Most lumps are harmless, but some signs mean it is time to get checked. See your GP if a lump grows quickly, becomes painful, or changes in any way. Ask for a specialist review if a lump keeps coming back after being drained, or if it presses on a nerve and causes numbness, tingling or weakness in your fingers. Go to an emergency department if your hand becomes hot, red and swollen with spreading redness, or if you develop a fever, as these can signal an infection needing same-day care. Sudden numbness, colour change or coldness in your fingers also needs urgent assessment. If a lump feels hard and fixed in place rather than soft and mobile, ask for a specialist review so it can be identified properly.

Overview¶
Diagnostic Differentiation¶
- A detailed physical examination of the MCP region of the affected digit can distinguish between a flexor sheath ganglion, trigger digit, and Dupuytren's nodule [1].
Pediatric Ganglions¶
- In children aged <10 years, ganglions mainly occur on the volar wrist [3].
- In children aged <10 years, 69% to 79% of volar wrist ganglions display spontaneous regression within a span of 12-18 months [3].
- Pediatric ganglions of the hand have a greater rate of resolution than ganglions of the wrist [5].

- Performing at least 1 aspiration before surgical excision improves the cost-effectiveness of dorsal wrist ganglions treatment [2].
- Hand surgeons are divided regarding the need to immobilize the wrist after dorsal wrist ganglion excision [4].
- Routine midcarpal joint exploration during arthroscopic excision of dorsal wrist ganglions appeared to reduce recurrence at 1 year without negatively impacting patient outcomes [6].
- Open surgery continues to be an ineffective way of managing cystic soft tumours of the dorsal aspect of the wrist due to high recurrence rates [7].
- Higher postoperative pain intensity following dorsal wrist ganglion excision was associated with recurrence following previous surgery [8].

Rare Tumors and Anatomic Variations¶
- Giant cell tumors of the distal phalanx are extremely rare [9].
- Giant cell tumors of the distal phalanx require extensive en bloc excision to prevent local recurrence [9].
- Digit-sparing operations for giant cell tumors of the distal phalanx may fail to eradicate all tumor foci [9].
- Giant spindle cell lipoma involving a finger is a rare variant reported due to its unusual location [10].
- Awareness of anatomic variations such as a persistent median artery with a reversed palmaris longus and volar ganglion is valuable for surgeons operating on the upper extremity [11].
- Marginal excision appears to result in a good outcome with no recurrence at short- to medium-term follow-up for parosteal lipomas of the phalanges [13].
Background & Causes¶
Diagnostic History and Examination¶
- A careful history suggests the correct diagnosis in approximately 90% of patients with hand problems [14].
- The patient’s hand dominance, age, gender, occupation, and hobbies requiring hand dexterity or strength should be noted during the history [14].
- The approximate date of onset of symptoms and, if injury is the cause, the exact date and mechanism of injury should be recorded [14].
- Patients should be questioned about prior treatment and their perception of its effectiveness [14].
- Complaints regarding the nature of pain (sharp, aching, dull, or burning), night symptoms, aggravating and relieving factors, and timing relative to morning or end-of-day work should be detailed [14].
- Symptoms including numbness or tingling indicate a neurologic problem rather than a mechanical one [14].
- Specific motor difficulties, such as difficulty in writing or unscrewing jar tops, should be noted [14].
- The medical history should include prior hand injuries and systemic diseases such as rheumatoid arthritis, diabetes, endocrine disorders, renal disease, or vascular disease [14].
- Women of childbearing age should be questioned about recent pregnancies [14].
- Examination of the hand should begin with observation to assess vascular condition by noting finger color and nerve function by observing sudomotor function [14].
- The extent and timing of injury are suggested by the degree of swelling and ecymosis [14].
- The posture of the digits and wrist may signal tendon or bone disruption [14].
- A diagram of the hand is helpful in documenting abnormalities such as lumps, laceration sites, previous scars, amputated fingers, and areas of decreased sensation [14].
- The hand, wrist, and forearm are gently palpated to note temperature, moisture, and areas of tenderness [14].
- Circulation is assessed by capillary refill, where circulation should return within 3 seconds when the skin is blanched in the paronychial region [14].
- Passive and active range of motion of the shoulder, elbow, forearm, wrist, and hand are evaluated [14].
- The integrity of individual muscles should be documented during the examination [14].
Pediatric Ganglions¶
- Pediatric ganglions can be treated expectantly, with 69% to 79% displaying spontaneous regression within a span of 12-18 months [3].
Dorsal Wrist Ganglions¶
- Cystic soft tissue tumours of the dorsal aspect of the wrist have two distinct histological subtypes [7].
- Higher postoperative pain intensity was associated with recurrence following previous surgery, treatment of the dominant hand, higher baseline pain intensity, lower credibility the patient attributes to the treatment and longer symptom duration [8].
Volar Wrist Ganglions¶
- Operation-related complications after arthroscopic volar wrist ganglionectomy are associated with anatomical location distal to the bifurcation of the radial artery and concurrently penetrated up to the superficial fascia layer [33].
Other Lumps and Bumps¶
- Distinguishing between a flexor sheath ganglion, trigger digit, and Dupuytren's may be accomplished with a detailed physical examination of the MCP region of the affected digit [1].
- Giant cell tumors of the distal phalanx are extremely rare and require extensive en bloc excision to prevent local recurrence [9].
- Digit-sparing operations may fail to eradicate all tumor foci in giant cell tumors of the distal phalanx [9].
- An angiolipoma of the hand can be a cause of carpal tunnel syndrome [12].
Management¶
Diagnostic Evaluation¶
- A detailed physical examination of the MCP region can distinguish between a flexor sheath ganglion, trigger digit, and Dupuytren's nodule [1].
- Patients presenting with swelling along an affected tendon sheath, most commonly as a dorsal wrist mass, may have rheumatoid tenosynovitis, which feels irregular and diffuse compared to well-defined ganglia [18].
- Painful dorsal wrist swelling may be the presenting symptom in rheumatoid arthritis, where tenosynovial swelling can contribute to de Quervain disease, trigger finger, or carpal tunnel syndrome [20].
Non-Operative Management¶
- In children aged <10 years, ganglions mainly occur on the volar wrist and can be treated expectantly, with 69% to 79% displaying spontaneous regression within a span of 12-18 months [3].
- Performing at least 1 aspiration before surgical excision improves the cost-effectiveness of dorsal wrist ganglion treatment, as patient preferences may preclude routinely performing 2 aspirations [2].
- Patients who received steroids at the time of aspiration perceived lower rates of recurrence for dorsal carpal ganglions [29].
- Conservative management in rheumatoid tenosynovitis of the hand and wrist requires rheumatologic support for systemic pharmacologic management, with splinting serving an adjunctive role to relieve pain [18].
- Targeted corticosteroid injection into the tenosynovial inflammation is more effective than the administration of systemic corticosteroids for isolated tenosynovitis [18].
- Scar massage is widely used by hand therapists, though few respondents had received formal skills training or completed outcome measures regularly to formally evaluate its clinical efficacy or impact [15].
Operative Management¶
- Higher postoperative pain intensity following dorsal wrist ganglion excision was associated with recurrence following previous surgery, treatment of the dominant hand, higher baseline pain intensity, lower credibility the patient attributes to the treatment, and longer symptom duration [8].
- Giant cell tumors of the distal phalanx require extensive en bloc excision to prevent local recurrence, as digit-sparing operations may fail to eradicate all tumor foci [9].
- Both curettage and resection/amputation are acceptable treatment options for giant cell tumour of bone in the hand, with treatment decisions individualized based on site and extent of disease to minimize morbidity while maximizing disease control [30].
- Surgical treatment for rheumatoid tenosynovitis involves removing the inflamed tenosynovium while preserving normal structures, a procedure shown to decrease pain and improve disease outcomes [18].
- Dorsal synovectomy of the wrist may be of lasting benefit if synovitis is moderate, bone changes are absent, but pain is significant, and persistent swelling continues for 6 weeks or longer despite adequate medical treatment [20].
- Dorsal synovectomy may be considered a prophylactic measure to avoid extensor tendon rupture in rheumatoid arthritis [20].
- Palmar (flexor) tenosynovectomy may be useful in relieving pain and preventing tendon rupture if hypertrophy of the volar wrist tenosynovium is obvious clinically with or without symptoms of median nerve compression [20].
- Surgical intervention for the rheumatoid wrist should be considered if the carpus is subluxated with a prominent ulna associated with local synovitis of the ulnar tendons and/or distal radioulnar joint [21].
- The indication for rheumatoid wrist surgery is mainly based on clinical and radiographic findings, with wrist stabilization given precedence even for oligosymptomatic patients when relevant risk factors for future deterioration are present [21].
